The WDL-PRO VHF Wireless System pairs the new AZDEN WR32-PRO Dual-Chanel Receiver with two (2) of the WM-PRO belt pack transmitters and the EX-503 lavalier microphones. This kit allows for a convenient wireless filming option for the on-camera subjects, recording high-quality audio with the lavalier microphones, which hook directly to the subject's shirt or shirt collar. This set-up is ideal for outdoor videos, weddings or even on-camera interviews.
